IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent N 0. [87,416, datedFebruary 13, 1877; application filed January 27, 1877.

To all whom it may concern:

Be it known that I, JACOB W. RIDER, of Altoona, in the county of Blairand State of Pennsylvania, have invented a new and valuable Improvementin Pumps; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1. of the drawings is a representation of a central verticalsection of my pump, and Fig. 2 is a transverse sectional view thereof.

This invention relates to force-pumps, and consists in the construction,combination, and arrangement of the devices hereinafter set forth.

In the accompanying drawings, A designates a pump-post, verticallyslotted near its upper end, to allow the vibration of pumphandles oroperating-levers, B B, which are pivoted on a cross-rod, B and the' longarms of which extend in opposite directions. Each one of said handles orlevers is provided with a vertical perforation, b, near the end of itsshort arm, and with a similar perforation, b, in its long arm, aboutequally distant from its pivot. O U designate two piston-rods, which arerespectively attached to said pump-handles or operating-levers, B and Bby means of small eyeholts, c c. To the lower ends of said piston-rodsare attached pistons, D D, operating respectively in pump-cylinders orcasings, E and E. Said pistons are preferably made of thick leather orother soft material, and are detachably connected to said rods, so thatnew ones may be substituted for those which have become worn. Theentrance of said pistons into said cylinders or casings is facilitatedby flaring funnel-shaped guidepieces, F, one of which is secured uponthe rim of the open top of each pump-cylinder or casing. Each one ofsaid cylinders is provided at its bottom with an induction-orifice, g,covered by an inwardly-opening valve, G,-and also with adischarge-orifice, h, covered by an outwardly-opening valve, H. Throughsaid' discharge-orifices h h said pump-cylinders E E' communicate withpump-tube I, which extends downward from pump-post A, and which may bemade in one piece therewith. Thus, whenever one of the pistons D or D ismade to descend, a current of water (previously admitted into thecylinder below said piston) is expelled through said tube 1. The descentof said pistons depends upon their attachment to the pump-handleshereinbefore described. If such attachment is made by inserting theshanks of eyebolts c 0 into perforations b b of the long arms of saidlevers or pump-handles, as shown,) each descent of said handles willorce down the said pistons. The two pistons and cylinders will thenoperate independently of each other, and two separate streams may beejected from the same pump, as hereinafter more fully described. Bothpiston-rods O 0 may, however, be attached to the same pump-handle, theone at b, the other at b, when the elevation of the long arm of saidhandle will operate one piston, and the depression of said arm of saidhandle will operate the other. Again, said piston-rods may be attachedto the short arms of the operating levers or pump-handles at b b, but,in that case, it is necessary, in order to work the pump advantageously,to adapt its piston s, cylinders, eduction-orifices, valves, &c., tolifting instead of forcing. J is a curved guidecasing or flanged plate,which is bent around pump-post A, and secured thereto. Said casing isprovided with two diverging discharge-tubes, KL, which communicatethrough perforations or outlets, k l, (as shown in Fig. 2,) with theupper end of tube I. In said guide-casing J, or in the space between thesame and said pump-post A, works a similarly-curved slide, L, which isprovided with small handles or catch-pieces, l, at each end, and alsowith several perforations, l. The arrangement of said perforations issuch that the flow of water can be cut off from either discharge-tube,or both of said tubes, or neither, at the will ofan operator, at eitherend of said slide. When both of said discharge-tubes are left open, twoindependent streams of water will be ejected in different directions.This will be found especially useful when the pump is located on thedividing line between two premises, so that two neighbors can draw watersimultaneously from the same pump without interference. In case of fire,or whenever for any other reason it is desirable to throw a stream farinto the air, one of said dischargetubes, K L, is closed, and thepistons D I) are operated alternately, so as to force a continuousstream of water rapidly through the remaining outlet. This may beeffected by using both pump-handles B B or only one of them, both thepiston-rods U 0 being attached thereto, as already described. Thislatter arrangement will be found useful in case only one person is onthe ground.

What I claim as new, and desire to secure by Letters Patent, is

1. In combination with the pump-handles B B both pivoted to the samecross-rod, B and each perforated at b and b, on opposite sides of saidcross-rod, the piston-rods O O, pistons D D, pump-cylinders E E, andtube I, substantially as described and for the purpose set forth.

2. The combination of two pump-handles, two piston-rods and pistons, twopump-cylinders, a vertical tube 1, and two dischargetubes connectedtherewith, whereby two persons can operate the same pump simultaneously,and draw water therefrom separately, substantially as set forth.

3. The combination of guide-plate or casing J, discharge-tubes K L, anda perforated slide L, adapted to be operated from either end and toclose either, both, or neither of the said discharge-tubes,substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
